Barometric Pressure Offline vs Model Scale Calculator

Track barometric pressure today and forecasts anywhere. Barometric Pressure Offline turns your device into a powerful barometer, altimeter, forecast, and pressure tracker. Check today’s barometric pressure, follow changing trends, explore upcoming forecasts, and keep a personal history wherever you go. Live pressure and altitude readings come directly from your device sensors, so the barometer works even when you’re offline. Perfect for hiking, sailing, travel, outdoor activities, weather tracking, or simply understanding how atmospheric pressure changes throughout the day. Key Features: ▶ Offline Barometer & Altimeter – Measure barometric pressure, sea-level pressure, and altitude directly from your device sensors without an internet connection. ▶ Pressure Forecast – See what’s ahead with interactive forecasts for Today, 72 hours, 7 days, or 16 days. Explore hourly pressure values, daily minimums and maximums, pressure tendency, and predicted rapid pressure changes. ▶ Pressure Change Alerts – Get notified when your device detects a significant pressure rise or drop, or when rapid changes are predicted in the upcoming forecast. Control barometer and forecast alerts independently, and tap a notification to jump directly to the relevant reading or forecast. ▶ Siri & Shortcuts – Ask Siri for pressure readings, forecasts, history, summaries, notes, and upcoming pressure changes. Use Shortcuts to access Barometer actions and build pressure tracking into your own automations. ▶ Spotlight Search – Find Barometer readings, forecasts, history, and other relevant content directly from Spotlight, then open straight to the corresponding reading, chart, or forecast. ▶ Migraine & Headache Tracker – Add notes to your pressure history and compare changes over time with migraines, headaches, joint pain, asthma, arthritis, or other pressure-sensitive symptoms. ▶ Pressure History – Look back at previous barometric pressure readings, trends, altitude measurements, and personal notes to better understand how conditions have changed. ▶ Export Your Data – Export pressure history and notes to CSV or JSON for your own analysis, records, or comparisons. ▶ Widgets – Keep current barometric pressure, recent history, trends, and forecast charts visible from your Home Screen and Lock Screen, including enhanced chart widgets and a portrait forecast layout. ▶ CarPlay Support – Check relevant pressure information while using CarPlay, with improved support for quick access on the road. ▶ Designed for the Latest Apple Platforms – Enjoy resizable layouts, enhanced widget appearances, clearer charts, improved navigation, and a responsive experience across supported screen sizes. No account is required, and your sensor history stays on your device. Fresh forecast data requires an internet connection, while downloaded forecasts can remain available when you’re offline. Whether you’re watching today’s weather, tracking an approaching pressure change, checking altitude on a hike, preparing for time on the water, or keeping a migraine and headache log, Barometric Pressure Offline puts the information you need in one clear, easy-to-use app. Track pressure now. Understand the trend. See what’s coming next. Terms of service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

A scale converter for people who build models. Pick a scale — HO, N, O, 1:35 armour, 28mm heroic, 1/4" = 1' — type a dimension, and read the answer as you type. Free, offline, no account, no ads. THREE ANSWERS, ONE SCREEN • Real → model — how big is a 40-foot boxcar in HO? • Model → real — this part measures 92 mm; what is that full size? • What scale is this? — give a real length and the model length it has to come out at, and get the ratio. COMPARE ACROSS SCALES A second view takes one measurement and shows it in every scale in a hobby group at once — model railway gauges, military armour, aircraft, tabletop miniatures — with a proportional bar per row so you can judge the sizes by eye instead of reading numbers. UNITS HOBBYISTS ACTUALLY TYPE It parses what you would write on a workbench note: 250mm, 2.5 cm, 5' 6", 5ft 6in, 1 1/2", 3/4", 1-1/2". Feet-and-inches and fractional inches are first-class output formats, not an afterthought — fractions come back as fractions, rounded to the precision you choose. SCALES INCLUDED • Model railways — Z, N, TT, HO, OO, S, O, G and more • Military and armour — 1:16, 1:35, 1:48, 1:72 • Aircraft — 1:32, 1:48, 1:72, 1:144 • Cars — 1:18, 1:24, 1:43, 1:64 • Tabletop and wargaming — 15mm, 28mm heroic, 32mm, 54mm • Architecture — imperial drawing scales like 1/4" = 1' and metric 1:50, 1:100 • Any custom ratio you type WORKS COMPLETELY OFFLINE No account, no sign-in, no sync, no paywall and no advertising. Every calculation happens on your device, and nothing you type is ever sent anywhere. The only thing the app ever sends is anonymous usage data — which scales and modes get used — and you can switch that off in Settings. For model railroaders, scale modellers, miniature painters, RC builders, dollhouse makers, architects and anyone who has ever stood in a hobby shop doing long division on their phone.
